ID3 2.4 can cause various MP3 players, especially on vehicles or even computers, not to play or at least not to display the ID3 tags.
In many cases though, since ID3 2.4 is much different than version 2.3, it will cause some players, especially in cars like Lexus not to play. Even on the computer, you may notice if you check the properties of the MP3 that it won't open or show any details (eg. frequency, bitrate and ID3 tags).
One symptom of this in a vehicle (eg. Leuxs,........
This normally works but if not use my mencoder solution if the output video does not play past the joined time.
the contents of list.txt need to look like this:
file somefile.mp4
file somefile2.mp4
then run ffmpeg
ffmpeg -f concat -i list.txt -c copy CME-2-router-dial-peer-final.mp4
The result is almost instant joining since there is no video processing since we are........
grep -E servers1[2-6] somefile.txt
The 1 before the [ bracket means that the number must start with one and can be between 1 and [2-6] or in plain English between 12-16.

This just simply outputs what you need a username and password that can be used to authenticate from .htaccess
htpasswd -nb user password
user:Gnb6uE9Lp4gt2
If you want to write it straight to a file
htpasswd -cb /tmp/somefile.pw user password
How To Use This In .htaccess
AuthUserFile /tmp/somefile.pw

There are usually two reasons for this.
#1 The most common is that you need to enable the -r (recursive) flag with zip to make it recurse into directories.
So the solution is to use -r
zip -r somefile.zip yourfiles
#2 If you are using bash scripting based on ls without the full path or for some other reason the full path is missing, zip looks for the files in the current directory so this will always fail.........
tar -xvJf somefile.tar.xz
It is very annoying that so many are now using the .xz archive format as standard instead of .tar.gz but nevertheless above is how you would extract it with the "J" flag (not lower case j as that is for bz).........
This is useful in the case you are not properly logged in via an OpenVZ session or even a normal SSH session that you fear may go down(if the connection is broken the history is not saved).
Save your bash_history like this:
history -w ~/.bash_history
You can always change the above to another file eg /tm........
It is very simple and like this to test for the existence of file using bash scripting:
if [ -f /etc/somefile ]; then
echo "yes it exists"
fi........
It may be hard to find by Googling by it's really quite simple and quicker than reading dozens of man page entries.

Just replace the 5 with whatever line you want to be printed.........
I'm really starting to love ImageMagick, I've used it to mass convert/resize family photos with scripts and all kinds of handy things.
Today I just learned that you can create PDF files with it too, say if you have images scanned or anything else it's very simple:
convert *.jpeg output.pdf
You can replace jpg with whatever format your files are in. One thing to remember is that you can specify the order that the images/pages are added to the PDF manu........

Make sure you have the required tools:

Where you can e-mail your Asterisk box and it will fax it to the phone number in the subject line. The good news ends there, it is fairly undocumented and buggy.
Take for example how the documentation mentions you can invoke from the com........
The folder I was trying to archive is about 72GB, but much like rsync at about 17GB it chokes because of the filesize. What's with so many common and essential Linux tools having such limitations? I guess it is likely that the authors never wrote their code with the idea that files would be so large but it's still very annoying. It's important to stay on top of these limitations on production servers because I didn't realize what happened until I checked the file with "........
locate: command not found (slocate database needed)For some versions especially older ones like 3.x they might not have the "slocate" database.
Meaning a "locate somefile" command doesn't work.
Just install "slocate"
[code:1:d6d717421c]yum install slocate[/code:1:d6d717421c]
Then run:

And you're good to go :)........
